Description

ON DISTANCE is a powerful and advance distance measuring set for quick distance estimation and measurement. It performs non-contact distance measurement by using camera and hardware sensors of device.

ON Distance combines the two most useful distance measuring modes in one app, which is Manual Distance and Auto Distance. Each measuring modes operate differently with a few significant features cater for your needs in different situation and occasion. It can also be used to measure object height and object length if you know the distance to the target object.

ON Distance is very useful especially for outdoor and sport activities. For example, measure the distance from wall to wall, distance to the golf stick, distance to the archery target, distance from home plate to the pitcher mound, distance to a building, distance to your friend, distance to a boat, height of any object, etc.

Mode 1: MANUAL DISTANCEManual Distance measure the distance to the target object with known length. You can also measure the length and dimension of target object if you know the distance to the object. For perfect accuracy, users are requested to do calibration only one time after the application is installed.

Mode 2: AUTO DISTANCEAuto Distance measure the distance to the target object automatically by aim the cameras at the base of the object. It works in camera live view. Auto Measure uses the height of the camera lens and its tilt angle to calculate the distance to the object. You can continue measure the height of object by lock the distance and aim the cameras at the top of target object. The only parameter required in this mode is the lens height, which is the height of your camera height to the base plane.

For more details information about how to use the app, please refer User Guide in this app.

★ 5x Zoom ViewZoom View feature with 5x magnifier helps you align the points on object boundaries accurately. The Zoom View is located at the right bottom of the screen.

★ Save MeasurementIt lets you save your current measurement in Manual Distance mode including images, all the measurement data, unit and all information related.in a file located in SD card. You can open the measurement in future for review or continue edit.

★ Open measurementYou can open your previously saved measurements for review or continue edit.

ACCURACY:The accuracy of this apps is highly depends on how well the user move the points to aligned with object boundaries when doing calibration or measuring. Please be noted that small error in calibration might causes large inaccurate in measurements. Accuracy also relies on the device sensor. From so many experiment we have done so far, the average accuracy of Manual Distance is falls between (+)(-)3% and accuracy for Auto Distance is between (+)(-)7.5%. Please use Auto Distance for quick distance estimation where accuracy is not critical.

Impressive I'm pleased with both modes. My only wish is that I could set multiple height presets for auto mode (maybe I'm standing sometimes and sitting other times, or maybe someone shorter than me is using my phone). But I don't think this is a big enough issue to dock the app any stars.

Smart Measure is a tool in the 2nd set of the Smart Tools collection.This rangefinder(telemeter) measures the distance and height of a target with your phone by trigonometry.

Usage is simple : just stand up and press the shutter. The important point is aiming the camera at the GROUND, NOT the object. (i.e. In order to measure the distance from someone, aim at his shoes.)

If it is inaccurate, please read the instructions in this app or see the checklist diagram in the blog. Because the sensors on your phone can be changed depending on OS version, firmware and battery status. You can calibrate them with the calibrate menu and settings for yourself.

This range-finder(telemeter) measures the distance to a target by the camera perspective. The effective distance is 10m-1km. To measure the distance, you should know the height(width) of a target.

Don't worry!! Man's height is 1.7m(5.6ft), a golf flag is 7ft, a bus is 3.2m(10.5ft), a door is 2.1m(7ft). With that, we can guess the height(width) of almost everything.If you know the airplane model, you can measure the height from the sky. For reference, Boeing 747's width is 72 meters.

Usage is simple. Input the height of the target, and touch the screen. If the target is aligned by 2 lines, get the measured distance.

This application allows you to measure the length of a path on the map.

Create the path by tapping the map. Different modes of path creating are available: direct, driving, walking and bicycling. Direct mode draws straight lines between points. Driving, walking and bicycling modes are able to find and follow roads between points. Driving mode finds routes using the roads network. Walking mode uses pedestrian paths and sidewalks (where available). Bicycle mode uses bicycle tracks and preferred streets (this is currently available only in US). Distance between first and last point is shown on the top of the screen. It is possible to get your current location. It is also possible to save and load routes.

Check vertical and horizontal alignments.Measure distances and angles.Take a picture, save it as as 3D scene in the library to work with it later.Export it as an image to share it with other people.

Watch the video to learn how to use this application in one minute.

Several shapes of plumb-bob are available:- a vertical or horizontal grid to measure sizes and proportions,- a vertical or horizontal frame split into 2 parts that can be resized independently to check that something is properly centered,- a 3D box or a cylinder (paid version only) to measure volumes,- a triangle to measure angles to the vertical,- a cone (paid version only).

To take a picture and freeze the background image, click on the camera icon.

The second button from the left of the top menu bar is used to alternatively display side buttons:- buttons to adjust the size, position or orientation of the plumb-bob shapes,- buttons to activate different touch modes to use gestures to either resize, move or rotate the plumb-bob shapes,- buttons to adjust the camera height (this height is used to estimate the other distances).

There is a wizard button to help you to adjust the camera height. If you know precisely the measure of an horizontal or vertical segment, make sure the frame is aligned to it, click on the wizard button and fill in with this known distance (the camera height will be automatically computed from this piece of information).

Use the settings button to:- select the front or back facing camera,- select the measurement unit,- adjust the frame line thickness,- define the number of rows and columns to display in the plumb-bob shapes,- increase the refresh rate of the sensor to get a smoother animation (paid version only).- change the colors (paid version only).- hide the label (paid version only).- change the label font size (paid version only).

Calibration:

The calibration page allows to adjust 2 parameters that are necessary to perform correct measurements: the angles of view of the camera, and the internal sensor calibration.

Camera angles of view: this information is normally reported by your phone. However, some manufacturers do not provide a valid value. In that case you must measure those angles manually and fill in the corresponding fields. If the invalid values are not corrected, the plumb-bob line will still be displayed vertically, but the frame sides will not.

Internal sensor calibration: click on the help button to access the related video tutorial.

This is work in progress. If you like this application, please give it a 5 stars rating.If this application does not work for you, please provide some feedback to the developer before giving it a low rating.

Map Distance Calculator application allows you to measure distances on a map by two ways. Firstly user can place pins on map and measure distance between consecutive pins. Secondly user can measure continuous path among points by pen tool. To do this user must click on map to place the pen first then long pressing on pen will activate the continuous drawing.

Metal Detector is in the 3rd set of the Smart Tools collection (EMF detector, ghost detector).

This app measures magnetic field value using the built-in magnetic sensor that is built into your device. The magnetic field level(EMF) in nature is about 49μT(micro tesla) or 490mG(milli gauss); 1μT = 10mG.If there is any metal in the area, the strength of the magnetic field should increase. Sometimes, this app used to find electrical wires in walls (like a stud finder) and iron pipes in the ground.

Usage is simple: Open this app on your device, and move it around. The magnetic field level will constantly fluctuate. That's it!

A lot of ghost hunters had downloaded this app, and they had experimented as a ghost detector.

The accuracy depends entirely on the sensor in your device. Note that the magnetic sensor is affected by electronic equipment (TV, PC, etc.) due to electromagnetic waves.

If this app does not work properly, it may mean that your phone's sensors are damaged, broken or non-existent. To initialize the sensors, point your phone up towards the sky and move it in a figure 8 pattern. Especially, a view cover with a magnet or a leather case with a magnetic snap can cause unwanted results.

Lastly, this app cannot detect gold, silver and coins made by copper. (They are classified as Non-ferrous that has no magnetic field.)

Camera measure: Telemeter is a bundle of tools for outdoor and indoor measurements for Android OS. The tools complement each other and are useful in such areas as distance measure, moving (use spirit level tool to adjust laundry machine), layout design, construction, room measurement and planning, house and room decoration and furnishing, trips and so on, where quick estimation of object dimensions, distance and size, orientation and exact horizontal, vertical or angular alignment are needed. Sometimes a traditional ruler or tape are very difficult to apply for long distances or big objects measurements. Telemeter is a very handy solution that can immediately estimate all these values for you using camera measure technique.

The distinctive feature of the Telemeter Tool is two options: - Hand-mode - Stand-mode

Choose Hand-Mode when the exact height of the camera is unknown and you are on the ground holding the device in you hands.Enter your height and smart algorithm estimates the camera height. You don't need to enter the exact camera height, as required in other applications. Since you know your height exactly, you can start measurements immediately. This is an advantage of using Hand-mode. This mode requires to hold and move your camera as shown in measurement guide that is included in the app.

If the exact height of the camera from the ground is known, Stand-Mode is to be used. Stand-mode doesn't make any assumption about your position. Exact camera height leads to more accurate measurement results. You can use this mode in different situations or build your own camera measurement setup.Measurements can be conducted in metric and imperial units: feet, meters, inches. Angles are measured in degrees.

With the Telemeter you can measure: - distance from you (observer) to an object - distance between points in direction 'from an observer' - distance between two points in a plane - object dimensions (depth, height, width, length) - height from the ground level - height of big objects or a person - angles between planes (e.g. between two walls) - angles between two orientations in the space - angles in horizontal or vertical planes

Please try also Partometer - camera measure App, that uses common reference objects for measurements.For long distance you can try Distance2Meter - camera measure that uses motion for distance measurement. You can measure distances in hundred meters range with good accuracy.

If you enjoy using this app, please take a moment to share your experience and rate it.

ON 2D-CameraMeasure is a powerful tool for object length, angle, area, diameter and dimension measuring. It lets you make measurement on any objects on a 2D plane. It can be used as or even replace ruler and measuring tape in many situation where the traditional measuring method is not enough or difficult to apply.

ON 2D-CameraMeasure is extra useful especially if you want to measure large object where simple ruler or measuring tape are difficult or impossible to apply. For example, size of large screen, height of a lamp post, dimension on a room plan, outer dimension of a building, angle of roof, area of a high window, dimension of a room, etc. It lets you measure anything in the fastest and easiest way as long as there is any known dimension as reference.

ON 2D-CameraMeasure performs non-contact measurement by using the device's camera and any known length or dimension as reference. The reference used in calibration can be length of a line, size of a rectangular object or diameter of a circular object. You can use the predefined common objects such as credit card, CD/DVD and A4 paper which is included in the application, or use your own custom object as reference.The reference object and measured object must be located on the same plane, which must be parallel to the camera surface plane.

It is simple to use, as the operational step below:Place the reference object on the same plane as measured object --> Capture picture with camera --> Calibrate --> Measure in different modes

For more details information about how to use the app, please refer User Guide in this app.

★ Save MeasurementIt lets you save your current measurement including screen image, measurement data in all modes, calibration data, length unit, current mode and all information related in a file located in SD card.

★ Open MeasurementIt lets you open the previously saved measurements for review or continue edit.

★ Import Image from GalleryIt lets you work with any photo or images in the gallery. You can make measurements on any image in gallery as long as there is a reference object with known dimension inside the image.

ACCURACY:The accuracy of this apps is highly depends on how well the user move the points to aligned with object boundaries when doing calibration or measuring. Please be noted that small error in calibration might causes large inaccurate in measurements. In order to achieve high accuracy, please try to use largest possible reference object. Larger object will be more easy to calibrate with less error. For example, please do not use credit card as reference object if you have A4 paper. From so many experiment we have done so far, the average accuracy is lie between (+)(-)1.5%.

ON 2D-CameraMeasure is totally free on android. We hope that this application can help more people to save time and simplify their measuring works, especially for those who are in the education, construction and engineering field.

ON DIAMETER is the best diameter measuring tool on android. This measuring tool will help you to measures the diameter and area of any circular objects on the device's screen.

This advance measuring tool let you measures objects that much larger than device screen size. From some experiment we have done so far, it can accurately measures the diameter of any circular objects up to 15 times longer than the screen length. For example, you can use it to measures the diameter of a compact disc, coins, round table, biscuits, masking tape, container cover, etc.

ON Diameter is so incredibly convenient and easy to use. You just need to place the measured object anywhere on the screen and move the 3 cross points to align with the object boundary. The object diameter and area will show on the screen automatically, as shown in the preview images. You can also switch the measurement unit between millimeter and inch by just a click.

For perfect accuracy, you will be requested to do calibration at the first time you open the application. Calibration need to be carried out only one time per installation. As we know, measure the diameter of large circular objects using ruler or measuring tape is a difficult task because we need to know the center point of the object or the two correct opposite points on the arc. This measuring tool can even measures the diameter of the object that larger than the total length of a measuring tape.

ON Diameter is the only android measuring tool application used to measures diameter. With ON Diameter, now you always bring a large caliper and measuring tape with you as in your smart phone.
